Two weeks ago me and my friends installed Borla headers, kinetix test pipes and greddy evo-2 exhaust. After that we put on motordynes 5/16" basic plenumspacer. Car works great and idle is alright but after driving it a bit the Check Engine Light comes on (it doesn't blink). So I drive home to my garage and reset the ecu (didn't do that right after the install). Start the car and the light is gone... So I drive it the next day and what the heck, CEL lights up again!

Anyone have any ideas on what we could have done wrong? Kinetix text pipes have oxygen sensors so it cant be those??? Maby a leek of some kind? Anyhow the car is going in to the nissan dealer for a standard service so hopefully they can see what's wrong with the consult.

 

Take it to AutoZone and have them check the CEL. It's free

 

It's from the test pipes, you're getting something like "catlyst something something something bank 1" I get them too with my test pipes. It's because the second set of sensors is reading the same as the first set so it knows your cats aren't functioning properly(or are gone as in this case).

 

mchong75: Might take me a while driving there from Sweden

So I'll just have to live with this?

 

The post-cat sensors are reading high emission levels. The SES light comes ON. It isn't too difficult to figure out.

 

Well, you have a one hell of a great trip ahead of you than.
I'll google map for you.

Mine came on when I installed the popcharger....it went away after a week or so.

It may go away on its way......

 

you can probably buy the 'STOP' non-fouler plugs online...it's about $25 for 2 sets. I installed them when I did the exhaust and have driven 2-3K miles with no problems.

 

imagine that, a SES from test pipes, who would have thought it

 

hehe... maby a stupid question But on kinetix homepage it says Check Enginge Light wouldn't come on with them so maby I shouldn't believe everything I read. So where can I buy these "STOP" non-fouler plugs?

 

I got mine from Autozone, but I am pretty sure you can order from Midway or something like that. Just search the web for Help! non foulers spark plugs. The number should be 42002. There are steps to do this yourself all over the web. It is a pretty easy fix.
